Three questions I can't find answers to...

[HanzMcGiggles]

1. Is there a way to add a texture to just one custom stage without adding it to the rest?

2. I've seen someone make a spawn point where rolling crates come out of. How do you set spawn points for certain items in custom stages?

3. Is there a way to put the fish from the summit into other levels such as Delphino Plaza, windwaker, etc?

1) No. Custom stages all load off these 3 texture .pacs. Change 1, and all your custom stages will change. However, you could kind of create your own stage by model/texture importing kind of like what others are doing.
2) Brawlbox, I think.
3) Model swap the fish. However, this is just to make something look like the fish. It won't act like it. You could swap, for example, the big star at the tower in delphino plaza with the fish, but the only thing that will happen is that the star will look like the fish.
